The density of magnesium alloy is 1.7, which is only 21% of steel and 60% of aluminum alloy, and its light weight advantage is more obvious. In addition, a series of advantages of magnesium alloy, in the application of bicycles, it has high rigidity and high bending resistance; excellent shock absorption, absorbing shock and vibration, the shock absorption effect of magnesium is 25 times that of aluminum, making the bicycle have better Excellent riding comfort; Its high-temperature extrusion forming process is good, extruding thin-walled magnesium alloy pipe fittings can significantly reduce the weight of the vehicle; the material is non-polluting, and the secondary recycling is simple, which is a green material.
The important load-bearing structure of the bicycle is the frame, which is the part where the overall weight is concentrated. Therefore, it is necessary to choose a magnesium alloy frame that is double lightweight and has good comprehensive mechanical properties to reduce the weight and lightness of the bicycle.
Density, modulus of elasticity, tensile length, tensile strength, fracture strength, toughness – the mechanical performance parameters of the structural materials required for this series of bicycle frames, in the magnesium alloy after the control of trace impurities of magnesium, aluminum, zinc and manganese, After appropriate forming treatment methods and other measures, its tensile strength and hardness will be improved accordingly, and its strength and elastic modulus will also meet the requirements of the frame, and its own high damping coefficient can absorb impact energy and reduce the impact on the rider. Influence, prolong the life of the bicycle.
